BACKGROUND

Some standalone projectors are suspended from a ceiling and often require a wiring that is visible below the ceiling. Suspended projectors often interfere with the appearance of a room and may also be distracting to occupants. Some suspended projectors may also interfere with unobstructed views of occupants. Table top and other types of projectors may also take up space that can be used for other purposes and may also interfere with the appearance of the view.

Many light fixtures include a light source and may include other components such as a power source, a controller, wireless or wired communication capability, a heat sink, etc. Some of these lighting fixtures may be indoor lighting fixtures and others may be outdoor lighting fixtures. In some cases, the lighting fixtures may be ideally located or may have locations that support information projection. Thus, a solution that provides projection of light and images with no or minimal interference of a space may be desirable.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

In the following paragraphs, example embodiments will be described in further detail with reference to the figures. In the description, well known components, methods, and/or processing techniques are omitted or briefly described. Furthermore, reference to various feature(s) of the embodiments is not to suggest that all embodiments must include the referenced feature(s).

Turning now to the figures, example embodiments are described. FIG. 1 illustrates a system 100 of lighting and projector fixtures according to an example embodiment. In some example embodiments, the system 100 includes lighting and projector fixtures 102, 104, 106 that may be installed in a ceiling 110. One or more of the lighting and projector fixtures 102, 104, 106 may operate to provide light for illumination and to project information. For example, one or more of the lighting and projector fixtures 102, 104, 106 may provide light for illumination in one mode and may operate to project information in another mode. Alternatively, one or more of the lighting and projector fixtures 102, 104, 106 may be recessed lighting fixtures only or recessed projector fixtures only.

In some example embodiments, each lighting and projector fixture 102, 104, 106 may include lighting components and projector components as shown in FIG. 2. When operating as a lighting fixture, each lighting and projector fixture 102, 104, 106 may provide an illumination light. When operating as a projector fixture, each lighting and projector fixture 102, 104, 106 may project an image on a surface such as a wall 112 or a wall 118. Each lighting and projector fixture 102, 104, 106 may be capable of projecting images that are typically provided by standalone projectors. For example, each lighting and projector fixture 102, 104, 106 may project still images and moving images such as video. The images may also include 3-D image(s), such as a 3-D image of a person standing or sitting on a chair, etc. The terms image and images as used throughout this description include text, pictures, video, and other forms of visual information as may be contemplated by those of ordinary skill in the art with the benefit of this disclosure.

In some example embodiments, the images projected by the lighting and projector fixtures 102, 104, 106 may include information such as weather information, traffic information, safety information, instructions, directions, commercial information (e.g., advertisements, sales, etc.), still pictures, motion pictures, etc. To illustrate, the lighting and projector fixture 102 may project weather information 114 on the wall 112, and the lighting and projector fixture 106 may project a picture 116 on the wall 118.

In some example embodiments, each lighting and projector fixture 102, 104, 106 may include a light source that emits a light. For example, the light source may provide an illumination light when the respective lighting and projector fixture 102, 104, 106 operates as a lighting device and may provide a projection light when the respective lighting and projector fixture 102, 104, 106 operates as a projector device. The light source of each lighting and projector fixture 102, 104, 106 may include one or more light emitting diodes (LEDs). Each lighting and projector fixture 102, 104, 106 may also include a power source, such as an LED driver, that provides power to the light source that emits the light for illumination as well as for projection based on the power provided by the power source.

In some example embodiments, each lighting and projector fixture 102, 104, 106 may include a controller that controls the operation of the respective lighting and projector fixture 102, 104, 106. Each lighting and projector fixture 102, 104, 106 may also include a transceiver or another communication component that is used for wireless and/or wired communication between the lighting and projector fixture 102, 104, 106 and control devices, such as a processor 120 (e.g., a local server or a remote cloud server), a mobile device 124, a smart speaker 126, etc. For example, the transceiver of each lighting and projector fixture 102, 104, 106 may receive lighting related instructions and information as well as projection related instructions and information (e.g., an image to be projected on a wall, a screen, or another surface such as a floor or a table) from the processor 120, the mobile device 124, or a smart speaker 126. In some example embodiments, the lighting and projector fixture 102, 104, 106 may receive lighting related instructions and information from a control device directly (e.g., via Bluetooth Low Energy connection) or via a network device 122 (e.g., a wired and/or wireless router and/or gateway device).

To illustrate, instructions to turn on and off the lighting and projector fixtures 102, 104, 106 may be received by the respective transceiver and processed by the respective controller of the fixtures 102, 104, 106. As another example, instructions to set and adjust lighting intensity level, color temperature, and other characteristics of the lights provided by the lighting and projector fixtures 102, 104, 106 may be received by the respective transceivers and processed by the respective controllers.

In some example embodiments, one of the lighting and projector fixtures 102, 104, 106 may operate as a primary lighting and projector device that receives instructions and information from a control device and that communicates with the other lighting and projector fixtures based on the received instructions and information. For example, the lighting and projector fixture 102, 104, 106 may use network (e.g., Wi-Fi) addresses to communicate with each other. A control device, such as the mobile device 124, may also use the network addresses of the lighting and projector fixture 102, 104, 106 to communicate with the devices.

In some example embodiments, a wall switch or a similar device may be used to control the powering on and off the lighting and projector fixture 102, 104, 106. For example, images may be provided to one or more of the lighting and projector fixture 102, 104, 106 regardless of whether the lighting and projector fixture 102, 104, 106 are powered on. When the lighting and projector fixture 102, 104, 106 become powered on, the lighting and projector fixture 102, 104, 106 may start projecting the received image or images.

In some example embodiments, one or more of the lighting and projector fixtures 102, 104, 106 may include an integrated occupancy sensor (e.g., one or more motion sensors) or may be communicably coupled to one or more external occupancy sensors. For example, one or more occupancy sensors may control some operations of the lighting and projector fixtures 102, 104, 106, such as turning on and off and the projection of images at one or more of the lighting and projector fixtures 102, 104, 106 may depend on occupancy detection.

In some example embodiments, one or more of the lighting and projector fixtures 102, 104, 106 may include a diffuser. For example, the lighting and projector fixture 102 may include a diffuser 108. To illustrate with respect to the lighting and projector fixture 102, the diffuser 108 may be in the path of the light from the light source of the lighting and projector fixture 102 when the lighting and projector fixture 102 operates to provide the illumination light. The diffuser 108 may be moved out of the path of the light when the lighting and projector fixture 102 operates as a projector device. For example, the diffuser 108 may be mechanically or electromechanically moveable.

In some example embodiments, the position of the diffuser 108 may be remotely controllable. For example, the controller of the lighting and projector fixture 102 may control the position of the diffuser 108 in response to commands received by the transceiver of the lighting and projector fixture 102. In some example embodiments, the lighting and projector fixtures 104, 106 may each include a diffuser that can be used in a similar manner as described with respect to the diffuser 108.

In some example embodiments, the lighting and projector fixtures 102, 104, 106 may each include a heat sink that is used to dissipate heat. For example, by using a heat sink, use of a fan may be omitted or a smaller fan may be included in the lighting and projector fixtures 102, 104, 106.

By using the same light source to provide light for illumination as well as for projection of images, costs and challenges associated with installing a suspended projector may be reduced. In some example embodiments, the lighting and projector fixtures 102, 104, 106 may be recessed in the ceiling 100 as shown in FIG. 1 or may be recessed or otherwise installed behind another similar structure. By installing the lighting and projector fixtures 102, 104, 106 recessed in the ceiling 110, the lighting and projector fixtures 102, 104, 106 blend in with a space compared to projectors that are suspended from a ceiling or placed on a table or a similar structure.

In some example embodiments, only some of the lighting and projector fixtures 102, 104, 106 may operate as a projector device. For example, the lighting and projector fixture 106 may be a projection only device and the lighting and projector fixtures 102, 104 may be lighting only devices. As another example, the lighting and projector fixtures 102, 104 may be projection only devices and the lighting and projector fixture 106 may be a lighting only device. In some example embodiments, the lighting and projector fixtures 102, 104, 106 may each include a standalone projector device without departing from the scope of this disclosure. In some example embodiments, fewer or more lighting and projector fixtures than shown may be installed in the ceiling 110. In some example embodiments, two or more lighting and projector fixtures may project information on an area, such as the wall 112.

FIG. 2 illustrates a block diagram of a lighting and projector device 200 according to an example embodiment. In some example embodiments, the lighting and projector device 200 corresponds to or may be included in each of the lighting and projector fixtures 102, 104, 106 of FIG. 1. In some example embodiments, the lighting and projector device 200 may correspond to a projection only device, i.e., a projector device.

In some example embodiments, the lighting and projector device 200 may include a lighting and projector module 202, a power source 204, and a controller 206. The controller 206 may control the operation of the lighting and projector module 202 and the power source 204. For example, the controller 206 may include a microprocessor or a microcontroller that executes software code stored in a memory device of the lighting and projector device 200 to control the operations of the lighting and projector device 200. The power source 204 may provide power to the lighting and projector module 202. For example, the power source 204 may receive Alternating Current (AC) power and provide Direct Current (DC) power to the lighting and projector module 202 and to the controller 206.

In some example embodiments, the lighting and projector module 202 may operate to provide light for illumination in one mode and may operate to project information (e.g., weather information, traffic information, safety related information), an image (e.g., a picture), etc. in another mode. To illustrate, the lighting and projector module 202 includes a lighting module 210 and a projector module 212. The lighting module 210 may include a light source 214 that emits a light 226. The light source 214 may include one or more discrete LEDs, one or more organic LEDs (OLEDs), an LED chip on board that includes one or more discrete LEDs, and/or an array of discrete LEDs. In some alternative embodiments, the lighting module 210 may include another type of light source without departing from the scope of this disclosure.

The projector module 212 may include components that support a projection technology that is based on one or more LCD, DLP, laser, etc. The projector module 212 may output a light 228 that projects an image, such as information, a photograph, etc. on a surface. For example, the light 226 from the lighting module 210 may serve as the light used by the projector module 212 to output the light 228. That is, the projector module 212 may not include a separate light source that provides a light to project images. In some example embodiments, the projector module 212 may be oriented or adjustable to project the light 228 on a surface, such as a wall, a table, a floor, etc.

In some example embodiments, the entire or parts of the projector module 212 may be moved from the path of the light 226 such that the light 226 is used as an illumination light to illuminate an area such as a room. For example, the entire or parts of the projector module 212 may be mechanically or electromechanically moved when the lighting and projector module 202 operates to provide illumination light instead of projection of an image. Alternatively, the projector module 212 may pass the light 226 through unmodified by information or image such that the light 228 is a continuation of the light 226, where the light 228 serves as the illumination light. As another alternative, an image may be used to alter the light 226 to generate the light 228, where the light 228 serves as an illumination light.

In some example embodiments, the controller 206 may control the power source 204 to adjust the light 226 provided by the lighting module. For example, the intensity level, the correlated color temperature (CCT), etc. of the light may be controlled by the controller 206 by controlling the power source 204 via an electrical connection 216 (e.g., one or more electrical wires). The controller 206 may also control the projector module 212 via an electrical connection 218. For example, the controller 206 may provide to the projector module 212, via the electrical connection 218, the information, photograph, etc. to be projected by the lighting and projector module 202.

In some example embodiments, the controller 206 may include a transceiver 208 that is used for communication between the lighting and projector module 202 and a remote control device, such as a mobile device. For example, controller 206 may receive via the transceiver 208 lighting control instructions as well as an image to be projected by the lighting and projector module 202. The transceiver 208 may be a wired transceiver, a wireless transceiver, or a combination thereof. In some example embodiments, the transceiver 208 may be a receiver instead of a transceiver without departing from the scope of this disclosure.

In some example embodiments, the controller 206 may control whether the lighting and projector module 202 operates as a lighting fixture (i.e., to provide illumination light) or as a projector (i.e., to project an image). For example, the controller 206 may control the operation mode of the lighting and projector module 202 based on a user input received by the controller 206 via the transceiver 208.

In some example embodiments, the controller 206 may control a diffuser, such as the diffuser 108 of FIG. 1, to move the diffuser out of the path of the light 228 when the light 228 is used to project an image. For example, the controller 206 may control a motor or another device to move the diffuser in or out of the path of the light 226 or the light 228 depending on whether the lighting and projector module 202 is used to provide illumination light or to project an image.

In some example embodiments, the power source 204 may provide power to the controller 206 via an electrical connection 220. The power source 206 may also provide power to the lighting module 210 via an electrical connection 222 and to the projector module 212 via the electrical connection 224. For example, the power source 206 may include one or more AC/DC converters. The power source 206 may also include DC/DC converters that may be used to generate power appropriate for the particular components that are powered by the power source 204.

In some alternative embodiments, the components of the lighting and projector device 200 may be connected in a different configuration than shown without departing from the scope of this disclosure. In some alternative embodiments, the lighting and projector device 200 may include other components without departing from the scope of this disclosure. In some alternative embodiments, some of the components of the lighting and projector device 200 may be integrated into a single component without departing from the scope of this disclosure. In some alternative embodiments, some of the components of the lighting and projector device 200 may be replaced by multiple components without departing from the scope of this disclosure. In some alternative embodiments, the lighting and projector device 200 may correspond to a standard projector without departing from the scope of this disclosure.

FIG. 3 illustrates a lighting and projector fixture 300 including a recessed projector device 302 according to another example embodiment. In some example embodiments, the lighting and projector fixture 300 may correspond to each of the lighting and projector fixtures 102, 104, 106. In some example embodiments, the recessed projector device 302 may correspond to the lighting and projector device 200 shown in FIG. 2. In some example embodiments, the recessed projector device 302 may correspond to or may include a standard projector.

In some example embodiments, the lighting and projector fixture 300 includes a mounting frame 304. For example, the recessed projector device 302 may be positioned on the mounting frame 304. To illustrate, the recessed projector device 302 may be positioned on a surface 306 of the mounting frame 304. The mounting frame 304 is designed to be positioned on a ceiling 310 or behind the ceiling 310, wherein the recessed projector device 302 is positioned on the mounting frame 304 on an opposite side from the ceiling 310.

In some example embodiments, the mounting frame 304 may have an opening 308. For example, the opening 308 may be aligned with an opening 332 in the ceiling 310. The recessed projector device 302 may be positioned on the mounting frame 304 to project a light or an image 328 through the opening 308 toward a surface 330 (e.g., a table, a floor, etc.) below the ceiling 310 and the recessed projector device 302.

In some example embodiments, the recessed projector device 302 may include a protruding portion 312 that extends into the opening 308. For example, images projected by the recessed projector device 302 may exit the recessed projector device 302 through the protruding portion 312. To illustrate, a lens of the recessed projector device 302 may be positioned in the protruding portion 312. Alternatively, the recessed projector device 302 may be omitted, and a portion of the recessed projector device 302 through which images exit the recessed projector device 302 may be lined up with and may be flush with the opening 308.

In some example embodiments, the recessed projector device 302 may rest on the mounting frame 304 without being secured by a fastener or another device. For example, the recessed projector device 302 may be wide enough to rest on the surface 306 of the mounting frame 304 without tipping over or otherwise becoming misaligned with the opening 308.

In some example embodiments, the lighting and projector fixture 300 may include a receptacle box 304. For example, the receptacle box 314 may be attached to the mounting frame 304 by one or more fasteners or may be integrally formed with the mounting frame 304. The receptacle box may include a power receptacle 316 that is connected to one or more electrical cables inside the receptacle box 314. A plug 322 of a power cord 320 may be plugged into the receptacle 316 to provide power to the recessed projector device 302.

In some example embodiments, the recessed projector device 302 may communicate with other devices and systems wirelessly. For example, the recessed projector device 302 may use a transceiver, such as the transceiver 208, to wireless communicate with other devices, such as control devices and image sources, using, for example, one or more wireless communication standards (e.g., Wi-Fi, Bluetooth, etc.). In some example embodiments, the recessed projector device 302 may communicate with other devices and systems using a wired connection. For example, a communication cable 324 including a connector 326 may be connected to the recessed projector device 302, and the recessed projector device 302 may communicate with other devices and systems via the cable 324 using one or more communication standards (e.g., Ethernet). For example, the cable 324 may be a coax cable, a CAT-5e cable, etc.

In some example embodiments, the mounting frame 304 may be made from sheet metal or another suitable material as can be contemplated by those of ordinary skill in the art with the benefit of this disclosure. For example, the mounting frame 304 may be made by pressing, bending, cutting, etc. a sheet metal.

By placing the recessed projector device 302 behind the ceiling 310, costs associated with suspending a standalone projector may be avoided. Because of the general availability of electrical wiring behind ceilings, the time and effort required to install the recessed projector device 302 can be lower compared to suspended projectors. Placing the recessed projector device 302 behind the ceiling 310 can also result in lower interference with a space and better use of a space compared to suspended and other types of projectors.

In some example embodiments, the lighting and projector fixture 300 may include other components than shown without departing from the scope of this disclosure. In some alternative embodiments, one or more components of the lighting and projector fixture 300 may be omitted or replaced with one or more other components without departing from the scope of this disclosure. For example, the receptacle box 314 may be omitted or replaced, for example, by a junction box. As another example, the plug 322 may be omitted. In some alternative embodiments, the recessed projector device 302 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, the mounting frame 304 may have another shape than shown without departing from the scope of this disclosure. In some example embodiments, the recessed projector device 302 may be oriented to project the image 328 or a light in different directions than shown without departing from the scope of this disclosure.

FIG. 4 illustrates a lighting and projector fixture 400 including the recessed projector device 302 according to another example embodiment. In some example embodiments, the lighting and projector fixture 400 may correspond to each of the lighting and projector fixtures 102, 104, 106. In some example embodiments, the lighting and projector fixture 400 includes a mounting frame 402 and a mirror holder 404.

In some example embodiments, the recessed projector device 302 may be positioned on the mounting frame 402 in a similar manner as described with respect to FIG. 3. To illustrate, the recessed projector device 302 may rest on the mounting frame 402 and may be oriented to project an image 412 or a light (e.g., an illumination or a shaped light) through an opening in a ceiling 410. For example, an opening 408 in the mounting frame 402 may be at least partially aligned with the opening in the ceiling 410. The recessed projector device 302 may also be powered and may communicate with other devices in a similar manner as described with respect to FIG. 3.

In some example embodiments, a mirror 406 may be positioned in a cavity of the mirror holder 404. For example, the mirror 406 may be attached to the mirror holder 404 by one or more fasteners such as a glue, a clip, or other means as can be contemplated by those of ordinary skill in the art with the benefit of this disclosure. The mirror 406 may be positioned to reflect the image 412 that is projected by the recessed projector device 302. For example, the mirror 406 may reflect the image 412 to a different surface instead of, for example, the surface 330 that is directly below the recessed projector device 302. In some example embodiments, the mirror 406 may be positioned in the mirror holder 404 to reflect the image 428 up toward a surface of the ceiling 410. In some example embodiments, the mirror 406 may be a convex mirror.

In some example embodiments, the mirror holder 404 may be integrally formed in the mounting frame 402. For example, the mirror holder 404 may extend down through the opening in the ceiling 410. In some example embodiments, the mirror holder 404 may be attached to the mounting frame 402, for example, by one or more fasteners, by soldering, etc. In some example embodiments, the mirror holder 404 may be part of a trim that is attached to the mounting frame 404 or the ceiling 410.

In some example embodiments, the mirror holder 404 may have generally a shape of a half of a dome as illustrated in FIG. 4. Alternatively, the mirror holder 404 may have other shapes without departing from the scope of this disclosure. In some alternative embodiments, the mirror holder 404 may be omitted and the mirror 406 may be attached to the mounting frame 402 by other means without departing from the scope of this disclosure. In some alternative embodiments, the protruding portion 312 may be omitted without departing from the scope of this disclosure. For example, no part of the recessed projector device 302 may extend into the opening 408 in the mounting frame 402. In some example embodiments, the mounting frame 402 may be the mounting frame 304 shown in FIG. 3.

As can be seen in FIG. 16, the lighting and projector fixture 1500 requires a relatively small space in the side of the ceiling 1510 facing occupants, and thus, eliminates or reduces the interference that traditionally results from suspended or desktop projectors.

FIG. 17 illustrates a lighting and projector system 1700 including recessed projector devices according to another example embodiment. For example, the lighting and projector system 1700 may be similar to the system 100 of FIG. 1 and may operate in a substantially similar manner.

In some example embodiments, the system 1700 includes recessed projector devices 1702, 1704, 1706. For example, the recessed projector devices 1702, 1704, 1706 may each be one of the recessed lighting and projector fixtures (e.g., the fixture 400, the fixture 500, the fixture 900, etc.) described above and may be installed in a ceiling 1710 in a similar manner as described above. In some example embodiments, the recessed projector devices 1702, 1704, 1706 may be recessed in the ceiling 1710 and may be controllable by one or more control devices, such as a handheld device 1708, a smart speaker 1718, external or integrated occupancy sensors, etc.

In some example embodiments, lighting fixtures 1712, 1714, 1716 may be installed in the ceiling 1710. The lighting fixtures 1712, 1714, 1716 may each wired and/or wireless communication capability. For example, the lighting fixtures 1712, 1714, 1716 may be controllable by a control device, such as the handheld device 1708, the smart speaker 1718, external or integrated occupancy sensors, etc.

In some example embodiments, the handheld device 1708 may wirelessly communicate with the recessed projector devices 1702, 1704, 1706 and the lighting fixtures 1712, 1714, 1716 using one or more communication standards such as Wi-Fi, BLE, ZigBee, etc. For example, the handheld device 1708 may communicate with the recessed projector devices 1702, 1704, 1706 through a network device 1720 that may include a wired and/or wireless router, a gateway device for communication with the internet including cloud servers, etc.

In some example embodiments, a processor device 1722 may control operations of the projector devices 1702, 1704, 1706, for example, based on communications with the handheld device 1708, the smart speaker 1718, external or integrated occupancy sensors as well as the projector devices 1702, 1704, 1706. For example, the processor device 1722 may be a local server that serves as a central controller that communicates with the handheld device 1708, the smart speaker 1718, external or integrated occupancy sensors, and the projector devices 1702, 1704, 1706 via the network device 1720. Alternatively, the processor device 1722 may be a remote cloud server that communicates with the handheld device 1708, the smart speaker 1718, external or integrated occupancy sensors, and the projector devices 1702, 1704, 1706 through the network device 1720 and that operates in a similar manner as a local server. The processor device 1722 may communicate with and control operations of the lighting fixtures 1712, 1714, 1716 in a similar manner.

In some example embodiments, the recessed projector device 1702 is positioned to project an image or a light (e.g., a shaped light) on a surface 1724. The recessed projector device 1704 may be positioned to project an image or a light (e.g., a shaped light) on a surface 1726, and the recessed projector device 1706 is positioned to project an image or a light (e.g., a shaped light) on a surface 1728. In some example embodiments, the projector devices 1702, 1704, 1706 may each have a network address or identifier that can be used by other devices to communicate with the projector devices 1702, 1704, 1706. In some example embodiments, the lighting fixtures 1712, 1714, 1716 may also have network addresses or identifiers.

In some example embodiments, the handheld device 1708 (e.g., a mobile phone or a tablet) may include a control application 1730 that is executed by the handheld device 1708 to control operations of the projector devices 1702, 1704, 1706. For example, the control application 1730 may be configured, automatically or through a manual process, with the network addresses of the projector devices 1702, 1704, 1706 as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure.

In some example embodiments, a user may select a particular one of the projector devices 1702, 1704, 1706 using the control application 1730. For example, the control application 1730 may provide a drop-down menu or otherwise provide a list of the projector devices 1702, 1704, 1706 on the display screen of the handheld device 1708. The control application 1730 may provide input interfaces for use by a user to power on or off one or more of the projector devices 1702, 1704, 1706. The control application 1730 may also provide an input interface on the display screen of the handheld device 1708 to select casting of images from the handheld device 1708 to one or more of the projector devices 1702, 1704, 1706.

In some example embodiments, the handheld device 1708 may associate one or more network addresses of the projector devices 1702, 1704, 1706 with particular user inputs. For example, a user may configure the control application 1730 to make such associations. Alternatively or in addition, a user may update a default association of particular user inputs with network addresses of the projector devices 1702, 1704, 1706. For example, the control application 1730 may associate a swipe (e.g., using a finger or a stylus) of the touch-sensitive display screen toward a particular side (e.g., right side) of the display screen with a command for a particular one or more of the projector devices 1702, 1704, 1706 to project one or more images. In response to such a swipe of the display screen, the handheld device 1708 may transmit the command to the particular one or more of the projector devices 1702, 1704, 1706.

To illustrate, the projector device 1702 may be associated with a swipe to the top side of the handheld device 1708 (and, thus the top side of the display screen), and the handheld device 1708 may transmit a command to the projector device 1702 to project an image or a light. The projector device 1704 may be associated with a swipe to the left side of the handheld device 1708 in a similar manner, and the projector device 1706 may be associated with a swipe to the right side of the handheld device 1708 in a similar manner. Additional projector devices may be associated with swipes to particular corners of the handheld device 1708. In some alternative embodiments, more directionally specific swipes of the display screen of the handheld device 1708 may be associated with commands to the projector devices 1702, 1704, 1706. In some example embodiments, two same-direction swipes may result in one or more of the projector devices 1702, 1704, 1706 starting to project an image or a light in response to the first swipe and stopping the projection of the image in response to the second swipe. Two same-direction swipes may also result in one or more of the projector devices 1702, 1704, 1706 stopping the projection of an image or a light in response to the first swipe and starting to project an image or a light in response to the second swipe.

In some example embodiments, a particular swipe or user input may be associated with multiple or all projector devices of the lighting and projector system 1700 and may result in multiple or all of the projector devices 1702, 1704, 1706 projecting one or more images or stopping the projection of one or more images. In some example embodiments, the handheld device 1708 may send a command to a different one of the projector devices 1702, 1704, 1706 to project an image in response to a particular user input (e.g., a down swipe), where the handheld device 1708 sequences through the projector devices 1702, 1704, 1706.

In some example embodiments, a user input (e.g., a swipe) to select one or more of the projector devices 1702, 1704, 1706 to project one or more images may result in the handheld device 1708 sending one or more commands to the unselected ones of the projector devices 1702, 1704, 1706 to stop the projection of one or more images. For example, a user may change the projection of an image or images by the projector device 1702 to the projection of an image or images by the projector device 1704 by selecting the projector device 1704 (e.g., swiping left) on the handheld device 1708. Alternatively, the handheld device 1708 may send a command to particular ones of the projector devices 1702, 1704, 1706 to stop projections of images if a user provides an input to the handheld device 1708 indicating such an action.

In some example embodiments, the images projected by the projector devices 1702, 1704, 1706 may be provided to the projector devices 1702, 1704, 1706 regardless of whether the projector devices 1702, 1704, 1706 are powered on or instructed to project the images. For example, the video source (e.g., a video camera) may continuously provide a video feed to the projector devices 1702, 1704, 1706, and the particular one or more of the projector devices 1702, 1704, 1706 that are powered on or instructed to project images may project the image (e.g., the video).

In some alternative embodiments, the projector devices 1702, 1704, 1706 may each retrieve information (e.g., weather information, traffic information, etc.) from a source, such as a cloud server (e.g., the processor device 1722), in response to a respective command from the handheld device 1708. The projector devices 1702, 1704, 1706 project an image that includes the retrieved information. A command from the handheld device 1708 to project images may be a power on command or another command that results in the projector devices 1702, 1704, 1706 projecting images.

In some example embodiments, the projector devices 1702, 1704, 1706 may retrieve information (e.g., weather information, etc.) based on a timer included in or coupled to the projector devices 1702, 1704, 1706. The projector devices 1702, 1704, 1706 may project an image including the retrieved information when the projector devices 1702, 1704, 1706 receive a respective command from the handheld device 1708 to project images. In some example embodiments, a command to project an image may not include information about the type of image or the source of the image, and the image (e.g., weather information, traffic information, a video, etc.) may be provided to or retrieved by the projector devices 1702, 1704, 1706 independent of commands to project images.

In some example embodiments, the handheld device 1708 may wirelessly send a dim command to one or more of the lighting fixtures 1712, 1714, 1718 in response to receiving one or more user inputs selecting one or more of the projector devices 1702, 1704, 1706 to project one or more images or one or more lights. For example, the handheld device 1708 may send the dim command to one or more of the lighting fixtures 1712, 1714, 1718 before or after sending one or more commands to the projector devices 1702, 1704, 1706 to project one or more images in response to a user input. In some example embodiments, one or more of the projector devices 1702, 1704, 1706 may send a dim command to one or more of the lighting fixtures 1712, 1714, 1718 in response to receiving a command to project one or more images.

For example, the projector devices 1702, 1704, 1706 may be configured with the network address of the lighting fixtures 1712, 1714, 1716, and may send a targeted or a broadcast dim command. The lighting fixtures 1712, 1714, 1716 may dim their emitted lights to a particular intensity level in response to receiving the dim command. The lighting fixtures 1712, 1714, 1716 may undim their lights in response to receiving an undim command from the handheld device 1708 or from one or more of the projector devices 1702, 1704, 1706 that may send an undim command in response to receiving a command to stop projecting a light. In some example embodiments, dim and undim commands from the handheld device 1708 may have a higher priority than such commands from the projector devices 1702, 1704, 1706. In some example embodiments, dimming and undimming of lights from the lighting fixtures may be controlled by the processor device 1722, which may serve as a local control.

In some example embodiments, the smart speaker 1718 may control the projector devices 1702, 1704, 1706 in a similar manner as described with the handheld device 1708 where user inputs to the handheld device 1708 are replaced by vocal commands provided to the smart speaker 1718. In some example embodiments, the smart speaker 1718 may be configured, automatically or through a manual process by a user, with the network addresses of the projector devices 1702, 1704, 1706 and the lighting fixtures 1712, 1714, 1716 as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. Additional configuration of the smart speaker 1718, for example, to associate labels with one or more of the projector devices 1702, 1704, 1706 and the lighting fixtures 1712, 1714, 1716 may be performed by a user in a standard manner of configuring smart speakers.

In some example embodiments, the smart speaker 1718 (e.g., AMAZON ECHO, GOOGLE HOME, etc.) may transmit commands to the one or more projector devices 1702, 1704, 1706 in response to vocal commands. For example, the vocal commands may be instructions to power on, off, etc. the one or more projector devices 1702, 1704, 1706. The vocal commands may also be instructions to have one or more of the projector devices 1702, 1704, 1706 project one or more images. To illustrate, a vocal command may be to have the projector device 1702 project particular information, such as weather information, where the projector device 1702 is identified by label, network address, etc. In response the smart speaker 1718 may send a corresponding command to the projector device 1702.

In some example embodiments, the smart speaker 1718 may send the vocally received command to a cloud server, such as the processor device 1722, that can generate the appropriate commands to be sent to one or more of the projector devices 1702, 1704, 1706. In some example embodiments, the smart speaker 1718 may provide the network addresses of the projector devices 1702, 1704, 1706 and the lighting fixtures 1712, 1714, 1716 to the processor device 1722 (e.g., a cloud server) such that the processor device 1722 can send commands and information, video images, etc. (i.e., images) to the appropriate ones of the projector devices 1702, 1704, 1706.

In some example embodiments, the smart speaker 1718 or the processor device 1722 may send dim commands to one or more of the lighting fixtures 1712, 1714, 1716 in response to vocal commands received by the smart speaker 1718 to start projection of one or more images by one or more of the projector devices 1702, 1704, 1706. In some example embodiments, the smart speaker 1718 or the processor device 1722 may send undim commands to one or more of the lighting fixtures 1712, 1714, 1716 in response to vocal commands received by the smart speaker 1718 to stop projection of one or more images by one or more of the projector devices 1702, 1704, 1706.

In some alternative embodiments, the system 1700 may include more or fewer projector devices and lighting fixtures than shown without departing from the scope of this disclosure. For example, the system 1700 may include just one projector device without departing from the scope of this disclosure. In some alternative embodiments, the handheld device 1708 or the smart speaker 1718 may be omitted without departing from the scope of this disclosure. In some example embodiments, the network device 1720 and the processor device 1722 may be omitted without departing from the scope of this disclosure. In some alternative embodiments, the projector devices 1702, 1704, 1706 may be installed in a different configuration than shown without departing from the scope of this disclosure.

FIG. 18 illustrates a lighting and projector system 1800 including recessed projector devices according to another example embodiment. The lighting and projector system 1800 is substantially similar the lighting and projector system 1700 of FIG. 17 and may operate in a substantially similar manner. In some example embodiments, the handheld device 1708 may include a control application 1802 that is executed by the handheld device 1708 to control operations of the recessed projector devices 1702, 1704, 1706 in a similar manner as described above with respect to FIG. 17. The handheld device 1708 may execute the control application 1802 to perform operations described above with respect to FIG. 17. The handheld device 1708 may also execute the control application 1802 to control operations of the lighting fixtures 1712, 1714, 1716.

In some example embodiments, the handheld device 1708 may associate one or more network addresses of the projector devices 1702, 1704, 1706 with particular user inputs as described above with respect to FIG. 17. For example, the control application 1802 may associate a swipe (e.g., using a finger or a stylus) of the touch-sensitive display screen toward a particular cardinal direction (i.e., north, south, east, or west) with a particular one or more of the projector devices 1702, 1704, 1706 and/or a command for the particular one or more of the projector devices 1702, 1704, 1706 to project one or more images, to stop projection of images, etc. By configuring the handheld device 1708 to associate a particular cardinal direction with particular one or more of the projector devices 1702, 1704, 1706 (e.g., using network addresses), the handheld device 1708 can interpret swipes of the screen of the handheld device 1708 in the particular cardinal direction as being directed to the associated one or more of the projector devices 1702, 1704, 1706 regardless of the orientation of the handheld device 1708.

In some example embodiments, the handheld device 1708 may include components that enable the handheld device 1708 to identify cardinal directions of swipes of the touch-sensitive screen of the handheld device 1708. To illustrate, the handheld device 1708 may include a 3-axis accelerometer, a 3-axis gyroscope and a 3-axis geomagnetic sensor that enable the handheld device 1708 to identify cardinal directions of swipes of the touch-sensitive screen of the handheld device 1708 regardless of the orientation of the handheld device 1708. In response to such swipes of the display screen, the handheld device 1708 may transmit commands intended for one or more of the projector devices 1702, 1704, 1706.

In some example embodiments, the projector device 1702, 1704, and 1706 may be associated by the handheld device 1708 with swipes in the directions of north, west, and south, respectively. In some example embodiments, the handheld device 1708 may also be configured to associate one or more projector devices with swipes in intercardinal directions, i.e., northeast, southeast, southwest, and northwest. Swipes of the screen of the handheld device 1708 in an associated intercardinal direction may result in the handheld device 1708 transmitting a command to the associated projector device.

In some alternative embodiments, the system 1700 may include more or fewer projector devices and lighting fixtures than shown without departing from the scope of this disclosure. For example, the system 1700 may include just one projector device without departing from the scope of this disclosure. In some alternative embodiments, the handheld device 1708 or the smart speaker 1718 may be omitted without departing from the scope of this disclosure. In some example embodiments, the network device 1720 and the processor device 1722 may be omitted without departing from the scope of this disclosure. In some alternative embodiments, the projector devices 1702, 1704, 1706 may be installed in a different configuration than shown without departing from the scope of this disclosure.

FIG. 19 illustrates a lighting and projector system 1900 including recessed projector devices according to another example embodiment. In some example embodiments, the system 1900 includes projector devices 1902, 1904 and lighting fixtures 1912, 1914, 1922 that are recessed in a ceiling 1910. For example, the recessed projector devices 1902, 1904 may each be one of the recessed lighting and projector fixtures described above and may be installed in the ceiling 1910 in a similar manner as described above. The system 1900 may also include gesture recognition sensors 1916, 1918, 1920. For example, the gesture recognition sensor 1916 may be communicably coupled to the projector device 1904, and the gesture recognition sensor 1918 may be communicably coupled to the projector device 1902. For example, the gesture recognition sensor 1916 may be integrated into the projector device 1904, and the gesture recognition sensor 1918 may be integrated into the projector device 1902. The gesture recognition sensor 1920 may be communicably coupled with one or both of the projector devices 1902, 1904.

In some example embodiments, each of the gesture recognition sensors 1916, 1918, 1920 are capable of identifying and interpreting hand gestures, such as hand gestures 1928, 1930. Alternatively or in addition, the gesture recognition sensors 1916, 1918, 1920 may transmit gesture detection information to the processor device 1722, which may be a local controller or cloud server. For example, the gesture recognition sensors 1916, 1918, 1920 may communicate with the processor device 1722 through the network device 1720.

In some example embodiments, the gesture recognition sensors 1916, 1918, 1920 and/or the processor device 1722 may be configured to interpret particular hand gestures as being directed to one or more of the projector devices 1902, 1904 and/or as particular commands, such as a command to project an image or a light, to stop projection, etc. For example, in response to determining that a particular hand gesture is directed to the projector device 1902 and that it corresponds to a particular command, the gesture recognition sensor 1916 may provide the command to the projector device 1902. Alternatively, the gesture recognition sensor 1916 may provide information derived from the detected gesture to the projector device 1902, and the projector device 1902 can interpret the information to take the appropriate action, such as start projecting an image or a light, stop projection, retrieve information from a cloud server, etc. The other gesture recognition sensors 1918, 1920 may operate in a similar manner with other projector devices to control operations of one or more projector devices.

In some example embodiments, the processor device 1722 may process gesture detection information received from the gesture recognition sensors 1916, 1918, 1920 to identify and interpret hand gestures, and in response, transmit one or more corresponding commands (e.g., project an image, stop projection, etc.) to one or more of the projector devices 1902, 1904 depending on the interpretation of the gesture detection information by the processor device 1722. For example, the processor device 1722 may more reliably identify hand gestures by processing information from multiple gesture recognition sensors.

In some example embodiments, the projector device 1902 may project an image or a light on a surface 1924 in response to a hand gesture being interpreted as a command to project an image or a light. The projector device 1904 may project an image or a light on a surface 1926 in response to a hand gesture being interpreted as a command to project an image or a light. The projector devices 1902, 1904 similarly stop projection of images in response to the same hand gesture or a different hand gesture from the hand gesture that resulted in the projection of images.

In some example embodiments, one or more of the lighting fixtures 1912, 1914, 1922 may dim their lights in response to the projector devices 1902, 1904 projecting one or more images. For example, the projector devices 1902, 1904, the gesture recognition sensors 1916, 1918, 1920, and or the processor device 1722 may transmit dim and undim commands to the lighting fixtures 1912, 1914, 1922 depending on, for example, whether the projector devices 1902, 1904 are starting or stopping projecting images.

In some example embodiments, the system 1900 may include more or fewer projector devices and lighting fixtures than shown. In some example embodiments, some hand gestures may be associated with one projector device, and other hand gestures may be associated with another projector device. For example, a set of hand gestures may be associated with projecting an image or a light, stopping projecting of images, projecting particular images (e.g., weather information, etc.), and other operations related to the projector device 1902. Another set of hand gestures may be associated with similar operations related to the projector device 1904.

In some alternative embodiments, the network device 1720 and the processor device 1722 may be omitted without departing from the scope of this disclosure. In some alternative embodiments, the projector devices 1902, 1904, the gesture recognition sensors 1916, 1918, 1920, and the lighting fixtures 1912, 1914, 1922 may be installed in a different configuration than shown without departing from the scope of this disclosure.

FIG. 20 illustrates a lighting and projector system 2000 including recessed projector devices according to another example embodiment. In some example embodiments, the system 2000 includes recessed projector devices 2002, 2004. For example, the recessed projector devices 2002, 2006 may each be one of the recessed lighting and projector fixtures described above and may be installed in ceiling 2010, 2012 in a similar manner as described above. In some example embodiments, the system 2000 may also include occupancy sensors 2006, 2008. For example, the occupancy sensor 2006 may be integrated in the projector device 2002, and the occupancy sensor 2008 may be integrated in the projector device 2004. Alternatively, the occupancy sensors 2006, 2008 may be standalone sensors.

In some example embodiments, the occupancy sensors 2006, 2008 may each include one or more of a motion sensor, a Bluetooth Low Energy unit, visible light unit, a camera, etc. that can be used to detect occupancy of a space as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. For example, the occupancy sensors 2006, 2008 may be passive infrared sensors.

In some example embodiments, the recessed projector device 2002 may be positioned to project an image or a light on a surface 2018 in a room 2014, and the recessed projector device 2004 may be positioned to project an image or a light on a surface 2020 in a room 2016. In some example embodiments, the sensor 2006 may control operations of the recessed projector device 2002, and the sensor 2008 may control operations of the recessed projector device 2004.

To illustrate, the projector device 2002 may project an image or a light (e.g., a shaped light) in response to an occupancy detection by the occupancy sensor 2006. For example, the occupancy sensor 2006 may send a command or other detection indicator information to the projector device 2002 in response to detecting one or more occupants in the room 2014. The projector device 2002 may project an image or a light immediately or a period of time (e.g., 30 seconds) after receiving the command or information from the occupancy sensor 2006.

The projector device 2002 may stop projecting the image or the light when no detection of occupancy of the room 2014 is indicated by the occupancy sensor 2006 for a period of time (e.g., 20 minutes). In some example embodiments, the projector device 2002 may stop projecting the image or the light in the absence of a detection of occupants for a time period regardless of whether the projector device 2002 started projecting the image or the light in response to a detection by the sensor 2006.

In some example embodiments, the projector device 2004 may project an image or a light (e.g., a shaped light) in response to an occupancy detection by the occupancy sensor 2008. For example, the occupancy sensor 2008 may send a command or other detection indicator information to the projector device 2004 in response to detecting one or more occupants in the room 2016. The projector device 2004 may project an image or a light immediately or for a period of time (e.g., 20 seconds) after receiving the command or information from the occupancy sensor 2008.

The projector device 2004 may stop projecting the image or the light when no detection of occupancy of the room 2016 is indicated by the occupancy sensor 2008 for a period of time (e.g., 10 minutes). In some example embodiments, the projector device 2004 may stop projecting the image or the light in the absence of a detection of occupants for a time period regardless of whether the projector device 2004 started projecting the image or the light in response to a detection by the sensor 2008.

In some example embodiments, the source of the image projected by the recessed projector devices 2002, 2004 may be a video camera 2028 of a doorbell device 2022 or a video camera of a security system. For example, when a person 2026 rings the doorbell device 2022, the doorbell device 2022 may send a message or a command to one or both projector devices 2002, 2004 or to one or more other devices such as the sensors 2006, 2008, the processor device 1722 (operating as a local or cloud server), a handheld device, etc. The doorbell device 2022 may also send a video stream to the projector devices 2002, 2004 or to the processor device 1722, a handheld device, etc. When the sensor 2006 detects a person 2024 in the room 2014, the sensor 2006 may provide a command to the projector device 2002 to project an image or otherwise indicate the detection of one or more occupants to the projector device 2002. In response, the projector device 2002 may project the image (i.e., the video showing the person 2026). Because no occupants are detected by the sensor 2008, the projector device 2004 may not project the video showing the person 2026. If the person 2024 or another person enters the room 2016, the projector device 2004 may start projecting the video following the detection of the person 2024 or the other person by the sensor 2008.

In some example embodiments, the doorbell device 2022 and the projector devices 2002, 2004 may communicate through the network device 1720 or via wired connections. In some example embodiments, the sensors 2006, 2008 may send detection information to the processor device 1722 that may transmit one or more commands to the projector devices 2002, 2004 depending on the information from the sensor 2006, 2008. For example, the processor device 1722 may transmit a command to the projector device 2002 to project an image in response to the sensor 2006 indicating to the processor device 1722 a detection of one or more occupants. The processor device 1722 may transmit a command to the projector device 2004 to project an image in response to the sensor 2008 indicating to the processor device 1722 a detection of one or more occupants. The processor device 1722 may transmit a command to stop projecting an image if no indications of occupants are received for a period of time or if an indication of no occupants is received for a period of time.

To illustrate, the sensor 2006 may indicate the detection of one or more occupants to the processor device 1722. For example, the processor device 1722, which also receives a message when the person 2026 rings the doorbell device 2022, may send a command to the projector device 2002 to project the video steam based on both the occupancy detection by the sensor 2006 and the doorbell indication from the doorbell device 2022. The video stream may be provided to the projector device 2002 directly from the doorbell device 2002 or indirectly through the processor device 1722. The processor device 1722 may operate in a similar manner to control the operation of the projector device 2004. In some example embodiments, a handheld device, such as the handheld device 1708, may operate in a similar manner as the processor device 1722 to control the operation of the projector devices 2002, 2004. In some example embodiments, the projector devices 2002, 2004 may operate with a security system in a similar manner as described with respect to the doorbell device 2022.

In some example embodiments, the smart speaker 1718 may operate in a similar manner as described above to control operations of the projector devices 2002, 2004. In some example embodiments, a control device, such as the handheld device 1708, may be used in a similar manner as described above to control operations of the projector devices 2002, 2004. In some example embodiments, the projector devices 2002, 2004 may also be controlled based on time scheduled and/or timers. In some example embodiments, lighting fixtures in the rooms 2014, 2018 may be dimmed and undimmed in a similar manner as described above.

In some example embodiments, the system 2000 may include more or fewer projector devices and sensors than shown without departing from the scope of this disclosure. In some alternative embodiments, the network device 1720 and the processor device 1722 may be omitted without departing from the scope of this disclosure. In some alternative embodiments, the projector devices and sensors may be installed in a different configuration than shown without departing from the scope of this disclosure.

Referring to FIGS. 17-20, in some example embodiments, a method of operation of the lighting and projector systems 1700, 1800, 1900, 2000 may include receiving, by a first one of the recessed projector devices of the systems 1700, 1800, 1900, 2000, an image to be projected. For example, the image may be or may include weather information, traffic information, a video, a picture, etc. The image may be received from an image source such as a laptop, a handheld device, a cloud server, a local server, a video camera, etc. The method of operation of the lighting and projector systems 1700, 1800, 1900, 2000 may also include receiving, by a second one of the recessed projector devices of the systems, the image to be projected. For example, the second recessed projector device may receive the same image as received by the first recessed projector device from the same source or a different source. Alternatively, the second recessed projector device may receive a different image from the same source or a different source. The method may also include receiving, by the first recessed projector device, a command to project the image. For example, the command may be received from the handheld device 1708, the smart speaker 1718, one or more of the gesture recognition sensors 1916, 1918, 1920, the occupancy sensors 2006, 2008, a local or cloud controller (e.g., the processor device 1722), a security system, a doorbell device, etc. In response to the received command, the first recessed projector device may project the image on a surface (e.g., the surface 1724, 1924, 2018) below the first recessed projector device. The method may also include receiving by the second recessed projector device a second command to project the same or a different image. For example, the second command may be received from the handheld device 1708, the smart speaker 1718, one or more of the gesture recognition sensors 1916, 1918, 1920, the occupancy sensors 2006, 2008, a local or cloud controller (e.g., the processor device 1722), a security system, a doorbell device, etc. In response to the second command, the second recessed projector device may project the same or a different image on a surface (e.g., the surface 1726, 1926, 2020) below the second recessed projector device. In some example embodiments, the method may also include receiving, by the first recessed projector device, a third command to stop projecting the image and stopping projecting the image in response to the third command.

FIG. 21 illustrates the lighting and projector fixture 400 projecting a shaped light according to an example embodiment. FIGS. 22A-22F illustrate examples of shaped lights according to an example embodiment. In some example embodiments, the lighting and projector fixture 400 includes a projector device 302 (or another projector device) that can emit or project a shaped light 2102. For example, the shaped light 2102 may serve as an accent light for an artwork 2104, to provide directions, to provide particular color lights, etc. In some example embodiments, the shaped light may be a highly focused light. For example, the shaped light 2102 may correspond to one or more of the shaped lights shown in FIGS. 22A-22F. The shaped light 2102 may have different shapes that correspond to different areas of a poster, a painting, etc.

In some example embodiments, the shaped light 2102 may be a framed light, where the light is shaped as a frame. For example, the shaped light 2102 may be a framed light, such as the framed light shown in FIG. 22F, that can be projected as a frame of the artwork 2104 or may be used for other purposes without departing from the scope of this disclosure.

In some example embodiments, other lighting and projector fixtures described above (e.g., the lighting and projector fixtures 300, 500, 600, 900, etc.) may provide shaped lights including the shaped lights shown in FIGS. 22A-22F and framed lights. For example, shaped lights projected on a floor or a wall may be used to provide directions, for entertainment, etc. The lighting and projector fixture 400 may project the shaped light using a particular lens designed to produce the shaped light, a particular shape image, or other means as may be contemplated by those of ordinary skill in the art with the benefit of this disclosure.

FIG. 23 illustrates a lighting and projector system 2300 including a lighting and projector fixture 2302 according to another example embodiment.
